The Gloucester County Department of Health says there have been eight reported Hepatitis A cases in the last nine weeks. The health department usually only sees less than 10 cases a year.

The health department says the cases are not connected. They are urging residents to get vaccinated against the disease and offering free vaccinations for those without insurance.

The disease is usually spread when a person unknowingly ingests the virus from objects, food or drinks that are contaminated by small and undetected amounts of stool from an infected person. Hepatitis A can also spread from close personal contact with an infected person through sex or caring for someone who is sick.
